Two talks have been delivered in this course by Wajid. 

• What derivative tells us about the shape of the graph? In this talk, Wajid focuses on how derivatives can be used to check the nature of a function and sketch its graph. For more details see the slides HERE.

• How to sketch solution curves of ODEs without a solution? In this talk, Wajid introduced qualitative theory of DEs and as an example presented a geometric approach for visualising solution curves of ODEs without explicitly solving the ODEs. For more details, see the slides HERE.
